INFLUENCE OF RETRENCHMENT STRATEGY ON PERFORMANCE OF SAMEER AFRICA IN NAIROBI CITY COUNTY, KENYA
No full text<p><strong>Abstract:</strong> The entry of new competition from imported tires and independent suppliers has had a significant impact on operating costs in Sameer Africa. This impact has manifested itself in the form of lower sales volumes leading to lower profits. This study examined the influence of retrenchment strategy on performance of Sameer Africa in Nairobi City County, Kenya. The study applied a descriptive research design. The unit of analysis was Samer Africa in Nairobi City County, Kenya, and the unit of observation was 630 employees drawn from the following departments; Sales and Marketing, Operations, Human Resources, Information and Technology, Imports and Clearing, Audit and Risk Management. Proportional stratified sampling was used in the study to select samples from various subsets of the target population in order to ensure adequate representation of all cases. Simple random sample selection was used to select the sample size of 245 respondents. With the help of a semi-structured questionnaire, primary data was gathered. The questionnaire was piloted on 25 respondents from the same organization who weren't part of the main study in order to test its validity and reliability. The means and standard deviations of descriptive statistics were used to analyze quantitative data. The data were presented using tables and graphics. Correlation analysis and multiple analysis were used in inferential statistics to ascertain the relationship between the independent and dependent variables. The study discovered that the performance of Sameer Africa in Nairobi City County, Kenya, is positively and significantly impacted by reemployment strategy. The study concluded that retrenchment is a cost-management strategy that removes goods and services from the market and lessens competition. The study recommended that the management of the company can for divestment strategy is the case of severity of competition and the inability of the organization to cope with it.</p>

A Bayesian model for dynamic functional connectivity estimation in the human brain with structural priors
No full textStudies of dynamic functional connectivity have demonstrated that anatomical linkage is related to persistent functional connectivity. Bayesian models can leverage this connection by regularizing estimates of functional connectivity according to the strength of the corresponding structural connectivity. We proposed and evaluated the ability of such a model to recover covariance matrices. The model performed well in a high dimensional, small sample simulated setting. In addition, it exhibited robustness to temporal transformations and an ability to recover simulated data generated according to both discrete and continuous temporal dynamics. Finally, it outperformed sliding window baselines and anatomically un-informed baselines on estimating instantaneous covariances according to out-of-sample log likelihood on two task datasets.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-08-01The student, Sameer Manchanda, accepted the attached license on 2019-07-19 at 10:46.The student, Sameer Manchanda, submitted this Thesis for approval on 2019-07-19 at 10:50.This Thesis was approved for publication on 2019-07-19 at 11:21.DSpace SAF Submission Ingestion Package generated from Vireo submission #14389 on 2019-11-26 at 13:06:25Made available in DSpace on 2019-11-26T20:49:36Z (GMT).

Karadi 3
No full textMusic, poetry, storytelling, and lively color come together to make each of these book/cassette pairs attractive. Each tape starts with a song in which Karadi introduces himself as a teller of stories. Here Kapi, the good king of the monkeys, has warned them not to let any mangoes float downriver towards Benares. Korung, a bad monkey, lets one float down, and soon enough the king has sent boats upriver to find this wonderful fruit. When the king and his hunters arrive, Kapi understands that he must form part of a bridge to freedom for his threatened people. He does this, and the king in admiration stops his men from firing arrows at Kapi. Korung, the last across, dashes Kapi down, but he revives. When the king assures Kapi that his people can return, he forgives Korung and welcomes him back. The book and audio cassette come together in a cellophane package. Though I will list each pair under both books and audio cassettes, I will keep them together in their packages under books.Script & Direction by Shobha Viswanat
Studies in cooperative communication systems over fading channels
No full textSpatial diversity in wireless networks can be attained by the use of
cooperative transmission. Leveraging spatial diversity enhances the performance of
the system, similar to MIMO (Multiple-Input Multiple-Output) technologies, but
without the requirement of multiple antennas installed in a single mobile device. In
cooperative transmission, mobile devices share their antennas with each other, '
forming an indirect multiple antenna transmitter that provides spatial and transmit
diversity to the transmission. In this dissertation, we focus on analysing the
performance of cooperative communication systems with single/multiple users under
different fading channels with efficient transmission protocols at the relay.
First, we analyse a single relay model for a single user using cooperative
transmission. To attain cooperative diversity, Maximal Ratio Combining (MRC)
scheme has been employed at the destination. We then analyse how the relaying
protocols (Decode-Forward and Amplify-Forward) affect the message detection at
the destination. Through simulation results, we compare the BER (Bit Error Rate)
performance of the cooperative transmission affected by different fading models.
Next, we consider multiple users communicating with the same destination in
cooperative transmission. Two models, Single Dedicated Relay (SDR) and Single
Shared Relay (SSR), are analysed by implementing orthogonal codes for multiple
access and detection at the destination.
Based on the analysis of the simulation results we achieve, we conclude that
the cooperative cooperation performs better than the single transmission from source
to destination.Master of Science (Communications Engineering

Microchemical systems for kinetic studies of catalytic processes
No full textThesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemical Engineering, 2002.Includes bibliographical references.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Silicon microfabrication techniques and scale-up by replication have for decades fueled spectacular advances in the electronics industry. More recently, with the rise of microfluidics, microfabrication has enabled the development of microchemical systems for a variety of chemical and biological applications. This work focuses on the development of these systems for improved gas phase heterogeneous catalysis research. The catalyst development process often requires fundamental information such as reaction rate constants, activation energies, and reaction mechanisms to gauge and understand catalyst performance. To this end, we have examined the ability of microreactors with a variety of geometries to efficiently obtain accurate kinetic information. This work primarily focuses on microfabricated packed-bed reactors that utilize standard catalyst particles and briefly explores the use of membrane based reactors to obtain kinetic information. Initial studies with microfabricated packed-beds led to the development of a microfabricated silicon reactor that incorporates a novel cross-flow design with a short pass multiple flow-channel geometry to reduce the gradients that often confound kinetics in macroscale reactors. The cross-flow geometry minimizes pressure drop though the particle bed and incorporates a passive flow distribution system composed of an array of shallow flow channels. Combined experiments and modeling confirm the even distribution of flow across the wide catalyst bed with a pressure drop [approx.] 1600 times smaller than typical microfabricated packed-bed configurations.(cont.) Coupled with the inherent heat and mass transfer advantages at the sub-millimeter length scale achievable through microfabrication, the cross-flow microreactor has been shown to operate in near-gradientless conditions and is an advantageous design for catalyst testing. The ability of microfabricated packed-beds to obtain accurate catalytic information has been demonstrated through experiments with phosgene generation over activated carbon, and CO oxidation and acetylene hydrogenation over a variety of noble metals on alumina. The advantages of using microreactors for catalyst testing is quantitatively highlighted throughout this work.by Sameer K. Ajmera.Ph.D
Pre and post-monsoon seasonal variation of some heavy metal pollution in sediments of River Gomti in the Vicinity of Lucknow City, India
No full textThe concentration of heavy metals (Fe, As and Cu) was examine in riverbed sediments of Gomti river, Lucknow at selected sites in pre and post monsoon season for three consecutive years (2009-11). The concentration was ranged between (As: 0.07-0.7, Fe: 7462.00-7977.00, Cu: 10.98-36.73 μg g-1) in pre-monsoon and in post-monsoon metal concentration was ranged between (As: 0.05-0.07, Fe: 543.00-7797.00, Cu: 32.00-9. 23 μg g-1). Whereas Geo accumulation index (I geo), contamination factor (CF), US EPA guideline also apply to determine the readily toxicity. Fe and As pollution was found from negligible to low level while Cu leads from low to moderate pollution. Significant correlation found between the metals in pre and post-monsoon of studied years, in case of As it was found insignificant. Conservation and management plan is also suggest for contaminated sites.Keywords: Gomti River, Heavy metals, Contamination factor, Geo-accumulation inde
